Technical Specification
48Vin 5.0/3.3Vout 100W
Quarter
Brick Dual
The DQ65033QGL10 DualQor series is an indepen-
dently regulated dual output converter that uses the
industry standard quarter brick package size. The very
high efficiency is a result of SynQor’s patented topology
that uses synchronous rectification and an innovative
construction design to minimize heat dissipation and
allow extremely high power densities. The power dissi-
pated by the converter is so low that a heatsink is not
required, which saves cost, weight, height, and applica-
tion effort. All of the power and control components
are mounted to the multi-layer PCB substrate with high-
yield surface mount technology, resulting in a more reli-
able product.
Dual Output, High Efficiency, Isolated DC/DC Converter
DQ65033QGL10 Module
Mechanical Features
Industry standard pin-out configuration
Industry standard size: 1.45” x 2.3” (36.8x58.4mm)
Low profile of only 0.34” (8.64mm), permits better
airflow and smaller card pitch
Total weight: 1.1 oz (31 g), lower mass reduces
vibration and shock problems
Flanged pins designed to permit surface mount sol-
dering (avoid wave solder) using FPiP technique
Safety Features
2000V, 30 M
input-to-output isolation provides
input/output ground separation
UL/cUL 60950 recognized (US & Canada), basic
insulation rating
TUV certified to EN60950
Meets 72/23/EEC and 93/68/EEC directives
which facilitates CE Marking in user’s end product
Board and plastic components meet UL94V-0 flam-
mability requirements
Operational Features
Independently regulated outputs (separate control loops)
High efficiency, 88% at full rated load current
Delivers up to 100 Watts of output power with minimal
derating - no heatsink required
Wide input voltage range: 35V – 75V, with 100V
100ms input voltage transient capability
Fixed frequency switching provides predictable EMI
performance
No minimum load requirement means no preload resis-
tors required
Protection Features
Input under-voltage lockout disables converter at
low input voltage conditions
Output current limit and short circuit protection
protects converter and load from permanent damage
and consequent hazardous conditions
Active back bias limit prevents damage to convert-
er from external load induced pre-bias
Output over-voltage protection protects load from
damaging voltages
Thermal shutdown protects converter from abnor-
mal environmental conditions
Control Features
On/Off control referenced to input side (positive
and negative logic options are available)
Output voltage trim: +10%/-10%, permits custom
voltages and voltage margining. Optional sec-
ond trim pin allows independent trimming.
